RUSsEILI. HUFF, or

.Be it known that I, RUssELLII-UIT, a Vcitiz'en of the vUnited States, and resident 'of Detroit, Wayne county, State of Michigan,

have invented certain new and useful Improvements' Iin Transmission Gearing, of which the following 1S a specification. f

This invention relates to transmission Jgearing and the objects are to simplify the construction and arrange the mechanism so that all operating arts 4are entirely inclosed; to arrange tiie, gearing so that the gear box may be mounted on the frame; and to. mount the operating lever directly on a shaft which projects from the gear box or easing, all of the operative mechanism being housed. l i

The invention generally stated consists in change speed and reverse gearing, a easing inelosing all the said parts, a rocking and an'endwise movable. shaft projecting from the easing andy which rocks to move one of the gears and slides to move another. In this case the shaft rocksto sli-de the change speed gears and slides to operate the reverse gear.v The operating lever'moves along and transversely of a guide; in this particular instance it moves alongthe guide to operate -thechangespeed gears and transversely' of the same to operate the reverse gears. The

reverse gear `is lockedv in inoperative positiony during the rotative movement of the shaft jin' operating the change speed gears'so as to -Th1s locking 1s aceomprevent breakage.

)lished bothby mechanism inside'of th cas- Ing .and by the construction ofthe lever guide. -'The shaft is -mounted in :anti-fricftion-'bearings which allow the shaftto be given'both an endwise and a rocking'move ment. l f

l To all 'whom it may concern.' t A thereby. A casing comprising sections 12 and 13 is bolted to the cross Ibars 11 andprovided with a cover 14. A -driving shaft 15 extends into the casing and connects with the motor, While la driven shaft I16 connects with the'rear'axle by means of the usual universal joint vand differential mechanism. The driving and driven shafts are mounted 1n bearings 17 and 18 in the usual manner.

thereto a gear 19 which meshes with a gear 20 upon :a counter vshaft 21, this counter shaft being also provided with a pair of gears 22, 23. The driving shaft 15 is provided with a squared portion 24 and a reduced portion 25 mounted in a roller bearing cage in the lgear 19. A sliding sleeve 26 is provided with al pair of gearsfwhich e0- operate with the gears 22, 23 and with internal teeth in the gear 19. The mechanism so far described is of known construction and its operation iswell known to those skilled The-shoe 27 is mounted upon a sleeve 28 sliding upon a stationary shaft 29 mounted in the casing. This sleeve is provided with aseries ofrecesses y30 which 'coperate with a. spring pressedlatch 31 so as to latch the Patented Get. 14, 1 913.

The driven shaft has rigidly connectedv sleeve in a plurality of positions. An arm and is provided with a pi n 33 which engages a fork in an arm 34 rigidly connected toa split sleeve 35. This split sleeve is rigidly yconnected to a hollow operating 'shaft 36 by means of bolts 35` asl shown-in Fig.` 4. The shaft 36 is mounted for rockin-g and endwise movement in its bearings. These bearings comprise roller cages 37 and 38 mounted for'endwiseand `rotative movement in the sleeves 39 and 40, the sleeve 40 being mounted in an\extension 40 bolted to the main gear casing.

The sleeve 35"has formed thereon an' ex'- tension 41. A shank 42 is mounted in this extension and is provided with a reduced portion 42 uponwhich a sleeve 43 is clamped by` nuts 44.l A'flange 43 on the sleeve 43 prevents endwise movement of the Shank 42 relative to the sleeve 35 when the latter is secured on the shaft 36,--but the construction permits relative rotation of the shank .42 and shaft 36." The shank 42 has formed thereon a head 45 provided with a A shaft 32 `extends downwardly from the Sleeve 28 cation Serial. No. 49

is adapted to engage an adjustable stop 53. The operating shaft has rigidly secured thereto .an operating lever 54 which is guided in its movements by means of the side members 55, 56 `of the operating` lever guide. This operating lever guide, Wrliich is illustrated in F ig.v 5, is of the same construction as that shwn in m prior appli! ,455,51 May 6,1909. One of the side members has formed therein a recess 57 whiclipermits the o erating lever to be moved inwardly.'v T e' guide is mounted upon a bracket 58 secured vto the frame ofthe vehicle. `As' described-in `the application referred to, the position of the operating lever shown in Fig. 5 corresponds to the neutral position of the gears shown in Figs'. 1, 2 and 3. i

By moving thelever forwardly, thel shaft 36 will be rocked to-move thel sleeve 26 so as to mesh the gears thereon successively with the gear 22 on the counter shaft 21 and with the internal teeth on Athe gear ,19, the positions corresponding to the intermediate speed and direct drive. In order to obtain the low speed, thel operating lever is moved backwardly so as to rock the shaft and move the 'sleeve 26.and the gear thereon to mesh with the gear 23. During this movement of the operating lever, the reverse .gear is maintained in inoperative position, as shown in dotted lines 1n Fig. 1 and'in full lines in Fig. 3, by 'the` engagement of 'the lug l'witli the straight portion 47 The connection between the shank 42 andthe^shaft 36 allows free rotative movement of the shaft. In vorder to obtain the reverse A drive the operatinglever is moved to neutral positionand theninwardlyinto the recess yengage the lug and move the reverse gear 50 into engagement with'the gear 23 on the counter shaft and the gear on the sleeve 26.`

Referring toFig. 6 which shows a sli htly I modified .form of operating levr, a' s eeve 60 is rigidly connected to lthe shaft 36 andl the operating lever straddles thissleeve and is conected theretoby means of a pivot pin 59. The operating lever has an extension 61 provided with a segmentwhich engages 'a roove in abracket 63 ri dlysecured-to the rame.. The operation lo this opera-tin 1ever is substantially-thesame as' vinthe crm" `claim as new and desire position the sleeve l26 wil-l be in l.driven shafts@ counter shaft, gears .shown in yFi 5., During theback and forth movement o the lever in the guide the segment 62 Will slide in the groove, but when the operating lever is moved transversely into the recess 57, the lever will swing about thefsegment 62 as an axis and move the shaft 36 inwardly. v

It will be obvious that various changes `may be 'made in the details ofconstruction Withoutdeparting from this invention and itis therefore to be understood that this in,- vention is not to be limited to the specific construction shown.
